Hello Christian,

As you're basically using bridge overlay setup, then perhaps default ARP
suppression kicks in. You may try configuring crb-prixy-mac and check if
that helps.
See:

pics/ref/statement/crb-proxy-mac.html

Regards,
Wojciech

I&#39;m starting to study how to interconnect two data centers via<br>

a DCI connection between one of DC1&#39;s leafs and one of DC2&#39;s leafs.=
 I<br>
set up an eBGP session and started propagating routes to inject these<br>
